I'm working on a profile manager for iOS, where the user can enter a name, and add a profile photo.
The profile photo is either chosen from the Native 'Camera Roll', or Native 'Take a Photo'.
The photos are then cropped to a perfect square, and then rescaled to a res of 256 x 256.
Every time I import a photo from the gallery (or take one), the memory jumps from 30Mbs, to 180Mbs. Meaning each time I import a photo, it takes up 150Mbs of memory. Even though the end result of the image is 256 x 256.
Any suggestions why this may be happening?
Thanks.
--- UPDATE ---
When I relaunch the app, it automatically loads in the profile images (the 256 x 256 versions), and the app memory is fine. (30mb).
So it must be to do with my crop and rescale functions, right? (maybe cacheing the files when it converts?)
